CASTING APPARATUS.

Specification of Letters Patent.

Patented Jan. 11, 1921.

To all whom it may concern Be it known that I, FRANK R. STEVEN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in (lasting Apparatus, of which the following is a specification.

This invention relates to casting apparatus, and has forits object to provide a casting apparatus for use in connection with tilting hot metal containers, such for example as a hot metal car which will be charged with hot metal from a blast furnace and then moved to the casting pit to be discharged. The tendency at the present time in blast furnace plants is to use cars or ladles of as large capacity as possible, and in handling these large masses of hot metal, especially where the container is tilted to discharge its contents, as in the case of a tilting car, or a ladle carried by a crane, it is desired not only to handle the metal as quickly as possible, but also in such manner as not to splash.

The present invention has for its object to provide a movable trough which will be engaged by the pouring lip of a tilting car or ladle and depressed thereby as the metal discharges, the lower end of the trough being movably supported so as to discharge the metal onto the casting table at any position, and remaining in close contact with the container throughout the pouring. Although the invention is useful with either a ladle or a tilting car, it is shown herein in combination with the car, which will run upon tracks adjacent the trough and the trough must be so mounted as to clear the track when not in use, but be engaged by the spout of the car when the hot metal is to be poured. To this end, the trough is flexibly suspended from its upper end as by a cable and counterweight limited in lifting the trough so that the latter will clear the cars except when one has been stopped and has commenced to tilt.

In the accompanying drawing,

1 represents a tilting car carrying a tilting hot metal container body 2 provided with a spout 3, of any suitable construction, and running on a track 4. 5 represents a casting table or the like provided with a track 6 on which runs rollers 7 on the lower end of the trough 8. The upper end of the trough 8 is provided with laterally projecting pins 9 to which is secured a link 10, which latter is connected through a stop ring 11 to cable 12 running over pulleys 13 and counterweighted as at 14, thereby holding the trough nor-- mally in the position shown in solid lines so as to be clear of cars running on track 4. The pouring spout of the car is provided with one or more hooks 15 which engage the pins 9 when the car body has tilted to the position indicated by 16 before any metal has run out. As the car body tilts to its lower position indicated by 1?, the trough 8 moves to its lower dotted position indicated by 18, the roller 7 traveling along track 6. Throughout this movement, the trough is controlled by the car body or ladle, and held in engagement therewith by the book 15, so that no time is lost in positioning the trough to receive the metal as soon as it begins to flow, nor is any attention required during the flow, also no splash ofmetal is made as the metal flows from the container to the trough without appreciable drop, runs through the trough and flows from the lower end thereof without appreciable drop on to the casting table or into the receiving trough thereof. As soon as the car has been discharged, and returned to upright position, the hook 15 disengages from the trough, and the trough returns to its normal lifted position.

If a ladle carried on a crane is used, the ladle will be swung until its hook can engage the trough pin 9, and then the trough will be controlled in like manner as the ladle is tilted by means of the tilting tackle connected with the crane through a hook attached to the lower portion of the far side of the ladle.

Various changes and modifications may be made in the details herein described without departing from the scope of the appended claims.

What is claimed, is:

1. In casting apparatus, a counterweighted pouring trough held normally elevated at one end and having its other end supported to travel over the distributing table of the casting apparatus as the elevated end is engaged and lowered by engagement with the pouring spout of a tilting hot metal car.

2. In a casting plant, a track receiving a tilting hot metal car, a trough held normally elevated to clear the cars on the track but engageable by the pouring spout when the car is tilted, and means movably supporting the other end 01. the trough adjacent a casting table.

3. The combination with tiltable means for discharging hot metal or the like, of an inclined trough engageable and movable thereby to receive hot metal, and a casting table receiving the metal from the trough.

4. The combination with tiltable means for discharging hot metal or the like, of a trough suspended by one end to be engaged by said metal carrying means and controlled thereby during tilting, the other end of the trough being movably supported adjacent a casting table to permit control of the trough by the metal carrying means while dischargmg.

5. In combination with a casting table, an inclined trough slidably resting thereon at its lower end and having its upper end held elevated whereby the trough whenengaged and depressed by a tilting hot metal or the like container is controlled thereby.

6. In combination with a car carrying a hot metal containing body dumping on a fixed axis and having a spout and a hook adj acent the spout, of a trough engageable by the hook and depressible thereby as the spout tilts, and means movably supporting the lower end of the trough adjacent a metal distributing table receiving metal from the trough.

7. In a casting plant, a tiltable hot metal container provided with a pouring spout and a hook, and a flexibly supported movable trough having at its upper end means to be engaged by said hook and discharging hot metal at its lower end throughout the tilting discharging movement of the container.
